Variable hydraulic lifters for 440 engine

Ok, i did some research on that numbers.

The 47339E12 did not show up anything related to any converter brands.
The CH RG 130 seems a part number of the ring gear only, which seems to be manufactured by Sonnax Performance Converters. (the 130 stands for the 130 teeth)
This ring gear is being used on the CH-RK-4 converter kit, now this is a sold as a kit which still requires to be welded together.
Performance Converter Kit - CH-RK-4
This is a 10" Non lock-up unit for the 727 TF.

This is the exploded view of the unit, Item #17 ring gear has the part number as i found.
Chrysler 727, 10-3/4" NLU Performance Converter Torque Converter

So now i am wondering, would a company like Sonnax sell these kits to, for example B&M, and B&M will do the final assembly and maybe do some in-house modifications of their own?
And B&M will sell this as a final product under their own name?
But if this is the case the converter could be any brand, and depending on the brand specific modifications/assembly could have any stall speed.
It says it uses a GM245mm core, which is used on a wide variety of converters for not just for Chrysler but also other brands.
